I didn't realize that his right arm was damaged. That helps explain his style. http://www.amazon.com/Joe-Gans-Biography-American-Champion/dp/0786439947/ref=pd_bxgy_b_img_b
Schmeling injured his right hand in the 5th round, in the 06/27/29 fight, against Uzcudun, but still won the 15 round decision.
Honestly that is not a good thing. It makes fighters more predictable....of course no one really ever was able to take advantage of that on Frazier outside of Foreman, and surpisingly frazier struggled with tall 6'4 boxers Mathis and Bugner.
